In a bid to take all responsibility into its own hands, Mars chocolate has committed a billion dollars to tackle climate change.

The maker of Snickers, Twix, and M&Ms, has pledged to invest $1 billion over the next few years to fight climate change, which includes investment in renewable energy, food sourcing, cross-industry action groups, and farmers.

Their wind farms in Texas and Scotland already generate enough to power U.S. and U.K, and so the company Mars operations has already taken several steps in efforts to become more sustainable.

As reported by Fortune, Mars has pledged to add wind and solar farms to nine more countries by 2018. The company also promised to cut greenhouse gas emissions by 27% by 2025 and by 67% by 2050.

Mars was one of the companies that signed a letter in June urging President Trump not to withdraw from the Paris Climate Agreement.

Grant Reid, CEO of Mars, explained the rationale behind the investment, saying that “most scientists are saying there’s less than a 5% chance we will hit Paris agreement goals…which is catastrophic for the planet.”
